How to use parameters in "Neo4j Cypher"?

[podunk]

 

Hello dear Hop users!

 

Could you please tell me how to use parameters in "Neo4j Cypher"?

In Parameters tab I have:

 

productid (parameter), product_id (Field), Integer (Neo4j Type)

'product_id' comes from csv file collumn - hop earlier.

 

My query is something like:

 

MATCH path = (....)

WHERE (product.product_id = {productid})

 

 

Does not work although according to manual, 'parameter substitution (for example {MY_PARAMETER}' it should: https://hop.apache.org/manual/latest/pipeline/transforms/neo4j-cypher.html

I tried also:

 

WHERE (product.product_id = ${productid})

WHERE (product.product_id = ?)

 

None works

 

So, what is the correct syntax?

 

Regards!
